Powers+of+Ten

toc Each day you will be asked to explore a different power of ten. You will find these on the website in the table on the right hand side. Think about your power of ten in relation to size and space. Where you are able to, compare it to things that you know. As you work on the Powers of 10 website __post your wonderings, questions and answers on this page. __ You can come back and add as you find out new things. Please make sure you put your work after the correct heading (click below it) and use Heading 3 for your name-school. Remember to click **Save** as soon as you are finished.

Cam (Greytown)
Man alive that guys hand is a monster,I hope mine isn't like that. I mean it goes from 100,000,000 light years to 0.000001 ångstroms. thats what I'm talking about.

Dan Carlisle (Greytown)
Holy Guacamole thats like soo big its well, BIG, like AHHHHHHHHHHHHHHHHHHHHH

Madison,Greytown
Its big........

=Josie, Greytown= That movie made my head spin! Those numbers are far too big and far too small to understand!

Emma, Greytown
It was really creepy when they zoomed in on the hand too - it really puts things into perspective - I thought my room was big - but the earth isn't even that big comparatively!

Sophie, Greytown
That show made me wonder how anyone or any country could think they were big. Some of the numbers were so big or so small - I hadn't even heard of half of them!!!

Matthew, Greytown
That is huge. I thought that the world was big but it is tiny compared to the universe and when they went in on the mans hand I cant believe how small things are!!!!!!!!

Jelmer,Greytown

Kaden, Greytown
I didn't know we were in one of heaps of galaxies but man space is HUGE!!!

Measuring in meters, this power of ten is equal to 1 meter. Measuring in seconds, this power of ten equals 1 second. The Picnic rug picture in the movie starts at 10 to the power of zero which means that the rug must be 1 square meter wide.

Dan (4r[1$[3, Greytown
10 to the power of zero = 10 x 10, 0 times so it = 10/1m

Matthew, Greytown
10 to the power of 0 is 1 metre. Just watch the powers of ten movie to find that out.

Emma, Greytown
Ten to the power of zero is one, as in one metre or one second as Josie said. In comparison to the rest of the world, the power of ten movie made it clear that we are barely a pin prick in the universe. The rug they zoomed in on, one square metre, was not even visable after a few seconds of zooming out.

Sophie, Greytown
10 to the power of 0 is 1. That could be one metre, one second, one anything. You should watch [|this] video. We are so small!

Kaden, Greytown
10 to the power of 0 is 1 metre so 10 to the power of 1 is 10 metres etc etc

Jelmer,Greytown
10 to the power of 0 is 1

Dan (4r]1$]3
Greytown 10 to the power of 1 = 100 so ten to the power of 1/2 = 50

Sophie, Greytown
Oh I get... 10 to the power of 0 is 10 so 10 to the power of 1/2 is 5. Thanks Dan

=Matthew, Greytown= 10 to the power of 1 is 10 meters. This represents 10 seconds of time. 10 to the power of two is 100 meters. This represents 100 seconds on time.

Kaden, Greytown
10 to the power of 1 10 so if it is halved it becomes 5 so 10 to the power of 1/2 is 5

Jelmer,Greytown
10 to the power of 1 is 10 so then 10 to the power of 1/2 is 5

10 to the 3/4
=Josie, Greytown =

750 milliseconds 75cm squared

=Matthew, Greytown=

10 to the power of 3 is 1 kilometer. This represents 1000 seconds. 10 to the power of 4 is 10 kilometers. This represents 10,000 seconds.

Sophie, Greytown
10 to the power of 3/4 is... 75?

Dan (4r]1$]3
Greytown 10 to the power of 1 = 100 so ten to the power of 3/4 = 75

Kaden, Greytown
If 10 to the power 1/2 is 5 10 to the power 3/4 is 7.5

Jelmer,Greytown
3/4 is the same as 75% so 10 to the power of 3/4 is 7.5

10 to the 5/6

 * 10 to the power of 1 = 100, 100 divided by 6 = 16.67 x 5 = 83.35

=Matthew, Greytown= 10 to the power of 5 is 100 kilometers. This represents 100,000 seconds. 10 to the power of 6 is 1000 kilometers. This represents 1,000,000 seconds.

Kaden, Greytown
10 to the power of 5/6 is 8.3333333333 because if you divide 10 by 6 it is 1.666666666667 times by 5 = 8.333333333.

Jelmer,Greytown
10 to the power of 5/6

10 to the 7/8
Dan (4r]1$]3 10 to the power of 1 = 100, 100 divided by 8 = 12.5 x 7 = 87.5

Kaden, Greytown
10 divided by 8 = 1.25 times by 7 = 8.75 to there is your answer

Dan (4r]1$]3

 * 10 ÷ 10 = 1
 * 10 ÷ 10 ÷ 10 = 0.1

=Matthew, Greytown= 10 to the power of -1 is .1metres. 10 to the power of -2 is .01metres.

Kaden, Greytown
10 to the power of -1 is .1metres. 10 to the power of -2 is .01metres.

Dan (4r]1$]3
10 ÷ 4 x 3 = 7.5

=Matthew, Greytown=

10 to the power of -3 is .001metres. 10 to the power of -4 is .0001metres

Kaden, Greytown
It is the same as 10 to the power of 3/4 but you just subtract it from 0 so it is -7.5

Dan (4r]1$]3
10 ÷ 5 x 4 = 8

=Matthew, Greytown= 10 to the power of -4 is .00001metres. 10 to the power of -5 is .000001metres.

Kaden, Greytown
4/5 = 80/100 divide that by 10 that = 8/10 so it = -8

Dan (4r]1$]3
10 ÷ 8 x 7 = 8.75

=Matthew, Greytown= 10 to the power of -7 is .00000001metres. 10 to the power of -8 is .000000001metres.

Kaden, Greytown
It is the same as 10 to the power of 7/8 but you just subtract it from 0 so it = -8.75
